- Efficient implementation of your safety concepts
- Reliable functional safety
System architecture of the IO-Link Safety System
In the IO-Link Safety System, all components communicate via a standardised interface:
- The IO-Link Safety Master connects the controller to the field level.
- The IO-Link Safety field devices supply safe signals and diagnostic data, while safeguarding access points and danger zones.
All communication is transparent and seamless.
The result: a fully integrated system that makes planning, commissioning and operation significantly easier.

IO-Link Safety Safety light curtain
The safety light curtain PSENopt II Advanced IOLS communicates directly with the IO-Link Safety Master and offers reliable access guarding.
The Master is used to connect IO-Link Safety devices such as the IO-Link Safety control unit and IO-Link Safety light curtains.
IO-Link Safety uses 3-core, unshielded standard cable. Up to 25 Bytes of data are transmitted in two directions with IO-Link Safety, at up to 230.4 kbit/s. You will find this cable in the right lengths for your application in the Pilz portfolio.
With the Pilz configuration tool you can configure and set parameters for the IO-Link Safety Master and devices.
Whether it’s safe operation, safety gate monitoring or electrosensitive protective equipment – the IO-Link Safety system from Pilz supports the most diverse safety applications. The following examples provide an insight into typical application scenarios.
Practical application examples with IO-Link Safety
Packaging plant with access guarding
IO-Link Safety Master + Safety light curtain + Safety gate guarding = Less wiring and faster installation

EU Machinery Regulation from 20 January 2027 – Pilz Insights
Application of the EU Machinery Regulation 2023/1230 is mandatory from 20 January 2027. It came into force in all member states on 19 July 2023, twenty days after it was published in the Official Journal of the European Union. The Machinery Regulation (MR) contains more specific details and provides greater clarity on previously controversial issues. It also contains new aspects such as the growing importance of Industrial Security and digitisation. Machine manufacturers now have time in which to meet the new safety requirements on plant and machinery.
